How to use V_TEXT in 2.0.0

[lafleur]

Looks like I'm missing something here on using V_TEXT?

MyMessage TEXTMsg         (CHILD_ID,V_TEXT);      // 47
send(TEXTMsg.set("Alarm is Active", 0));     // Send to gateway

I get this error...

Using library MySensors at version 2.0.0-beta in folder: /Users/lafleur/Desktop/MySensor-Arduino-development/Arduino-development_1.6b/libraries/MySensors 
exit status 1
invalid conversion from 'const void*' to 'void*' [-fpermissive]

Thanks...

Hi!

I think you need to send a character array:

You can use the function toCharArray to convert a String to a character array.

What happens if you just skip the ",0", like this:
TEXTMsg.set("Alarm is Active")

@hek

That works?? what the ,0 for ??

Sorry, I don't know why you added ,0. :stuck_out_tongue_winking_eye:

For some of the msg setters, the second argument is used to specify length (buffer) or number of decimals (float).
